Answers to Activities Questions

1. f(x) = 3x   ;   

2.  g(x) = -x + 3     ;     

       Note this very special case. It is an example of a line with a slope of -1, and 
       any line with a slope of -1 will be perpendicular to the line y = x, which has a 
       slope of 1. Hence it will reflect in itself across that line.

3.   h(x) = 0.8(x - 2.3) + 3.2    ;   

4.      ;   

5.  p(x) = - 3    ;    x = - 3

6.     ;
